I have no idea what a DJL2 environment is, but if are able to set it up with the GUI, it should be pretty easy to set up with PowerTool. From a PowerShell window (on a system that has the latest PowerTool installed), issue the following commands:
ConnectTo-Ucs <ucs IP address>
Then within the GUI that opened go through the steps to create a VLAN. The output from the ConvertTo-UcsCmdlet should provide you with the basic PowerTool cmdlets that you would need to build into a script that would loop through all the VLANs you want to create. The VLAN to Fabric/Port-channel association can be built into a table in the script or you could create it as an XML file that is read by the script.
I'd be happy to help out if you haven't done any PowerShell scripting in the past.
